Which of the following is true for construct cell by `E_(Cu^(2+)|Cu)^(Theta)=+0.34V and E_(H^(+)|H_(2))^(Theta)=0` ?

Options

A. `Pt|H_(2(g))|H_((aq))^(+)(1M)||Cu_((aq))^(2+)(1M)|Cu_((S))`
B. `Pt|H_(2(g))(1" bar")|H_((aq))^(+)(1M)||Cu_((S))|Cu_((aq))^(2+)(1M)`
C. `Cu_((S))|Cu_((aq))^(2+)(1M)||H_((aq))^(+)(1M)|H_(2(a))(1" bar")|Pt`
D. `Pt|H_((aq))^(+)(1M)||H_(2(g))(1" bar")|Cu_((S))|Cu_((aq))^(2+)(1M)`
